This patchset adds FPGA image reload support on Intel PAC N3000 Card. Image reload means that a reload mechanism of an FPGA, BMC, or firmware image from FLASH or EEPROM after flash or program the images without power cycle the server. This patchset introduces 2 new sysfs files for query the available images and trigger a image reload. patch 1: add the available_images and image_load sysfs files. Write a key word into image_load sysfs file to trigger a reload of an FPGA, BMC, or firmware image from FLASH or EEPROM. patch 2: add a trigger to update a new Retimer firmware. v3: >From Lee Jones's comment, uses regmap_update_bits() API instead of the wrapper of m10bmc_sys_update_bits(). v2: add more detail about how to use the image_load sysfs files in ABI documentation.
